Upgrade requires 63MB extra space, but disk has 93BG free

[peterqb]

Software updater gives an error, requiring 63.1MB more space. It seemed unlikely to me, so I checked the disk use, and Properties reveals that there is 93.5GB free.

I followed the suggestion in the dbox to use 'sudo apt-get clean' but it made no difference.

Is there a way round this? Perhaps use terminal to upgrade? It seems strange that the updater should report this statistic.

TIA

Let me guess... It wants more space on the /boot partition but your free space is somewhere else. There are many threads about that, and a new one is started almost daily. Use google with this search string:

As Impavidus and I thought - /boot is filling up.

You need to remove old unused kernels.

http://ubuntuforums.org/showthread.php?t=2248684 is from a few days ago.

Personally I'd install and use synaptic for this.


dpkg -l linux-image-\* | grep ^ii in a terninal will give you some idea of the kernels you have installed.

Thanks for the reply.

I have managed to remove some of the old kernels. Found this on google: sudo apt-get autoremove -y && sudo reboot now

Cannot download synaptic, but if the commands I used sort it, then I can do that from time to time. Updates appear to be installing OK now.

Any way of increasing the boot partition and is this a good idea?

Thanks again.

The long and short of it is you installed with lvm/encryption - that creates a small /boot partition.

I don't use lvm nor have any experience with it - but there are ways to resize lvm - you can't use gparted to do so afaik.

Do that - then you'll be able to increase the size of /boot.

Make sure when you get upgrades that an kernel install triggers at least a memory for you to deal with older ones before you get the same issue again.

Just as a fyi - any apt-get clean or apt-get autoclean will be of no help at all in these circumstances, all they do is remove downloaded deb packages.

Thanks for the replies. The encryption was set automatically, ie I had no idea it was using this when I installed.

The 'sudo apt-get autoremove -y && sudo reboot now' seemed to do the trick, and I have kept a note of that in case I need it again.
